Slotted beads will slide around the bend of any hook, and they are heavier than countersunk beads because less metal has been removed from the spherical shape. They are also good to use with jig hooks on which the eye is offset at an angle to the shank. 20 beads per package.

Good weight but...

Very heavy beads. They get your fly down for sure! With the slot though, they become easily off-centered while tying, potentially leaving the slot exposed and the bead crooked. Just requires attention.

Very heavy

The bead for small gap hooks

These beads work great on TMC 200 type hooks (I use Eagle Claw L052 hooks which is the same design) without having to bend open the the hook and then resetting it, which could weaken the hook. I use them exclusively for my heavier patterns I want to get down quickly.
